The threat from Russia will remain even if Ukraine wins the war, the UK's Chief of General staff has warned. General Sir Patrick Sanders urged NATO's eastern flank to "never write off" Russia, saying that despite Moscow facing setbacks in its invasion, its "intent has been revealed to the world". "No matter how this war ends - and it must be through a Ukrainian victory - I believe the Russian threat will remain," he told the annual RUSI Land Warfare Conference. Paying tribute to Ukraine's bravery and sacrifice, he said it has given NATO time to "modernise", train, and ensure it is prepared, so it can deter Russia. "We must do more. We owe it to Ukraine," he said.
